1.4 Claims.

This invention relates to the winding-of yarn on tubes, cones or otheryarn carriers and more particularly it relates to an automaticallyoperated means for winding a r serve length of yarn on the end of thecarrier belore winding the yarn package.

It has been found advantageous to have a reserve length of yarn wound onthe carriers of yarn packages to serve as a transfer tail where the yarnis used on warping or knitting machines, but where the last operation ofpreparing the yarn package comprises a twisting operation.

the beginning of the winding there is usually at a short length of theyarn which is not uniformly twisted. It is, therefore, an object of thisinvention to provide automatic means for winding on the end of the yarncarrier a waste tail of sufficient length to include all thenon-uniformly twisted yarn at the start of the winding prior to windingthe usual transfer tail of reserve yarn, the two groups of turns of theyarn being spaced from each other and from the yarn package on thecarrier.

In the drawings, which illustrate a preferred embodiment of thisinvention,

Fig. l is a partial for winding a waste tail and a transfer tail inaccordance with this invention, the parts being positioned as at thestart of winding the waste turns;

Fig. 2 is a view similar to Fig. 1 and showing the parts as positionedduring the winding of the yarn package; Figs. 3 and 4 are partial viewsin elevation showing the relative positions of the yarn guides duringthe winding of the waste and transfer tails and during the winding ofthe yarn package, respectively;

Fig. 5 is a view in elevation of the ratchet wheels, cam and camfollower shown in Figs. 1 and 2; and

Fig. 6 is a fragmentary sectional view taken as on line 6-6 of Fig. 3.

.In the drawings, the invention is shown applied machine of knownconstruction, only such parts of the winding machine being shown as arenecessary to illustrate the application of the invention thereto. Of thewinding machine there is shown the driving rollers I mounted at oppositesides of the machine on shafts 2 supported in suitable shown) carried bythe machine frame which comprises a bed plate 4. The yarn carriers,shown as tubes, 6 on which the yarn is to be wound, are mounted uponshafts 8 supported so bearings (not plan view of a winding mathereon.The

that the carriers and theyarn wound thereon rest upon the drivingrollers l and are driven thereby. The yarn passes between each tube 6and its roll I and during the winding of the body of the package, the

is reciprocated throughout the winding operation so as to distribute theyarn on the tube.

To receive the waste and transfer turns of the is guided tothe groovesof each tube by means of a yarn guide l4 mounted on a bar l6 which issupported by spaced links l8 pivotally connected.

to the bar l6 and a bar carried by the machine frame. A spring 22connected to an end of the bar l6 and to the machine frame biases thebar Hi to a position as shown in Fig. 4, while a pin 24 mounted in anend of a lever arm 26 and engaging between pins 25 and 21 fixed in thebar I6 controls the movement of the bar I6.

The lever arm 26 is one arm of a substantially T-shaped lever pivotallymounted as at 28, on the bed plate 4 and having an arm 26' extending tothe opposite side with a pin 24' engaging between pins 25' and Z'l'fixed in a bar |6 to control the operation of the same simultaneouslywith the operation of the bar Hi, the bar [6' being mounted similarly tothe bar l6 and having yarn guides l4 mounted T-shaped lever is alsoprovided with a curved arm 30 having spaced pins 3| and 33 projectingupwardly therefrom at its outer sitioned inwardly from the pins 3| and33.

The cam follower 32is positioned to engage a cam 34 mounted for rotationabout a bolt 36 fixed in the bed plate 4. A spring 2| coiled about a hubattached to the cam and having one end engaged with the base plate 4 andits other end engaged with the cam 34, opposes the rotation of the camin a clockwise direction. The cam 34 is a fiat circular disk having anirregular sectorlike portion cut away and providing a circular cam face34| extending approximately 270 and a short cam face 342 of less radiusthan the larger cam face 34!. Bolts 38 and springs 39 surrounding thebolts yieldingly secure a stop member 23 to the cam 34 where the portionhas been cut away, the member 23 projecting radially of the cam 34 toengage with the cam follower 32.

Secured to the upper surface of the cam disk 34 is a ratchet wheel 40arranged to be engaged for operation vin a clockwise direction by a pawl43 p v tally mounted at an end of a lever 44 yarn is guided by a yarnguide In mounted upon the traverse bar l2 which of the machine andprovided to engage nalled in the machine frame.

shaft 56 is a lever arm 52 positioned to engage in Figs. 1 and 3, sothat the yarn to be wound in which is pivotally mounted on the bolt 36supporting the cam 34. A spring 46 engaging the pawl 42 and its pivotalsupport biases the pawl the ratchet wheel 46.

The opposite end a lever arm 46 fixed on a shaft 56 suitably jour- Alsofixed on the a cam 54 fixed on the roller shaft 2. A spring 56 securedto the upper end of the lever 46 and the adjacent end of the lever 44holds these levers in engagement while a spring 56 secured to the lever52 and to the machine frame tends to hold the lever 52 in engagementwith the cam 54. A locking dog 66 pivotally mounted on the bed plate 4is biased by a spring 62 to engage with the ratchet wheel 46 and preventrotation of the ratchet wheel and cam 34 in a counter-clockwisedirection by the spring 2|. Mounted on the dog 66 is an adjustableabutment 64 positioned in the plane of the lever arm 36.

When the mechanism is operating to wind the waste tail on the tube andthe parts are positioned as shown in Fig. 1, the follower 32 on lever 36bears against the cam face 34i at or adjacent the stop member 23, pawl42 is positioned to engage ratchet wheel 46, lever 52 bears against cam54 and pin 24 on lever 26 bears against pin 25 and holds bar 16 pressedto the right. as seen yarn guides M are alined with the outer grooves Edon the tubes 6 and the bar I6 is raised by the links [8 against theaction of spring 22. With the shaft 2 operated to rotate rolls i andtubes 6 to wind the yarn in the outer groove 6a of each tube 6, rotationof cam 54 operates lever 52, once for each revolution of shaft 2 and,through shaft 56, lever 48 and lever 44.operates the pawl 42 to rotatethe ratchet wheel 46 step by step in a clockwise direction and shift thecam 34 against the action of spring 2|. The winding of the yarn in theouter groove 6a continues as the cam 34 is moved around step by stepuntil the follower 32 passes from the cam face 34L As the follower 32passes from the cam face 341, spring 22 shifts the bar l6 to move theyarn guide l4 to the left until it is alined with the inner groove 6band at the same time, through the engagement of pin 25 with pin 24,shifts the levers 26, 36 so as to bring the follower 32 into contactwith the cam face 342. Cam face 342 limits the movement of the levers26, 36 and bar l6 and holds the yarn guide l4 alined with the innergroove 6b.

Continued operation of the shaft 2 causes the the groove 61) andcontinues the stepping around of the cam 34 until the cam face 342passes from beneath the follower 32 per mitting the spring 22 to shiftthe bar i6 further to the left and to cause the follower 32 to moveinto-the cutaway portion of the cam 34. This movement of lever 36 bringspin 33 against lever 44, causing lever 44'to rotate on the bolt 36 and,through spring 56, to rotate lever 46, shaft 56 and lever 52, liftinglever 52 from the cam 54 against the action of spring 58 and preventingfurther operation of the lever 52 by the cam .54. Locking dog 66 remainsin engagement with the of the lever 44 is engaged by package the yarnguide i4 from the groove 6b and, at the same time, lowers the bar i6 andyarn guide M as the supporting links l8 pivot about their connection tothe fixed bar 26. This movement of the yarn guide i4 positions the yarnto be engaged by the yarn guide l6, the yarn passing up the inclinedside of yarn guide l6 and being retained in the slot thereof. Continuedmovement of the yarn guide i6 thereupon distributes the yarn upon thetube 6 during the winding of the in the usual manner.

Upon replacement of filled tubes with empty tubes, the levers 26, 36 areoperated by means of handle 66, rotating the lever 36 about the pivot 28and shifting bar I6 to the right to raise the bar l6 and aline the yarnguide [4 with the groove 6a. Rotation of the lever 36 removes pin 33from the lever 44 and engages pin 3! with the pawl 42 to disengage thepawl from the ratchet wheel 46 permitting spring 58 to return lever 52to engagement with cam 54 and shifting levers 48 and 44 with lever 52.Continued movement of the lever 36 engages the lever with the abutment64 on the locking dog 66 and disengages the dog 66 from the ratchetwheel 46. Disengagement of the dog 66 from the ratchet wheel permits thespring 2i to rotate the cam 34 and ratchet wheel 46 counter-clockwiseuntil the stop member 23 on the cam 34 engages the cam follower 32, thuscausing the sam 34 to be returned to its starting position. The springs39 on bolt 38 cushion the blow of the stop member 23 and prevent damageto the various parts. The parts are now in starting position and uponplacing the yarn in the yarn guide 14 and securing the end of the yarnso it will wind upon the tube 6, the cycle of operations is repeated.

The return of the cam 34 to its initial position for the start of eachwinding operat on insures uniform lengths of the waste and transfertails being wound at each operation. When the yarn package is used,severing the yarn between the waste and transfer tails insures transfertails of uniform length and uniform twist throughout.
